Road noise?

Has anyone fixed the road noise on these trucks? Mine sounds like its coming from top of door frame but door gasket looks good.

Also where do ya add sound deadening? I was thinking of adding on roof,rear cab,doors and rear speaker tray.

Upgraded door seals help. Just remove the plane vinyl U channel from the body seam around the door, and replace with a set from an Isuzu trooper, or Honda Pilot. Takes 15 minutes tops.

Isn't the u channel seal same as classic mustangs it looks the same as my old 66?
